Human placenta, where life begins!❤️❤️
The placenta is a temporary organ found in eutherian female mammals while they are pregnant.
The placenta is connected to the fetus by the umbilical cord, which is made of blood vessels and connective tissue. When the fetus is delivered, the placenta is delivered afterwards. The placenta is often called the afterbirth.❤️❤️

Tornwaldt cyst is a rare cyst in the midline of the nasopharynx that may become infected. It is a remnant of the embryonal notochord superficial to the superior constrictor muscle of the pharynx and is covered by the mucous membrane of the nasopharynx. It may become infected, causing persistent purulent drainage with a foul taste and odor, eustachian tube obstruction, and sore throat.
Purulent exudate may be seen at the opening of the cyst.
Diagnosis is based on nasopharyngoscopy supplemented by CT or MRI when the diagnosis is in doubt.
Treatment consists of marsupialization or excision.

Sperm Cells approach the Ovum.
Surrounding the Ovum are the cumulus cells. In order for fertilization to occur, the sperm must penetrate through the layer of cumulus cells. An abundance of cumulus cells is necessary for the development of a healthy embryo, as they provide the necessary nutrients and energy for oocyte maturation.
